Titanium: Cov khoom tseem ceeb rau Satellite Manufacturing
Nyob rau hauv lub maj mam chanting ntawm ancient paj huam, lub ntug yog ib txwm endowed nrog endowed reverie thiab romance. Niaj hnub no, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, satellites, raws li cov neeg xa xov ntawm tib neeg kev tshawb nrhiav ntawm lub ntiaj teb, xa mus rau lub hiav txwv loj ntawm cov hnub qub, xa cov ntaub ntawv, qhia cov lus qhia, thiab huab cua huab cua, dhau los ua ib feem tseem ceeb ntawm peb lub neej. Tom qab qhov kev ua tiav no, titanium hlau, nrog nws qhov tshwj xeeb ntxim nyiam, tau dhau los ua cov khoom tseem ceeb hauv kev tsim satellite.
1. Lub teeb yuag thiab lub zog siab los tiv thaiv cov teeb meem hnyav
Txoj kev taug kev ntawm satellites yog qhov kev sim ntawm cov nplaim taws los ntawm qhov chaw, thiab kev taug kev nyob ib leeg ntsib qhov nqus ntawm qhov chaw thiab qhov kub thiab txias sib txawv. Titanium hlau, nrog nws qhov tsawg ntom ntom, siab zog thiab siab melting point, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov khoom siv satellite. Nyob rau ntawm "skeleton" ntawm lub satellite, TB2 high-strength titanium alloy tsim ib tug loj-caliber ob chav corrugated plhaub qauv thiab apogee cav bracket, muab lub satellite nrog ruaj khov thiab muaj zog zog. Nyob rau hauv "lub hnub qub-rocket txuas txoj siv" nruab nrab ntawm lub satellite thiab lub tsheb tso tawm, lub teeb yuag thiab lub zog muaj zog ntawm titanium hlau txo lub nra thaum lub sij hawm tso tawm, txo cov roj noj, thiab tso cai rau satellites ya mus rau hauv qhov chaw sib sib zog nqus yooj yim dua.
2. Nickel-titanium alloy: "tus neeg saib xyuas nco" ntawm satellites
Ntawm ntau cov titanium alloys, npib tsib xee-titanium alloy yog nto moo rau nws cov cim cim xeeb muaj nuj nqi. Cov hlau no tuaj yeem rov qab mus rau nws cov duab qub nyob rau hauv qhov kub thiab txias lossis sab nraud quab yuam, ib yam li cov khawv koob ntawm kev nco. Hauv kev tsim cov kav hlau txais xov satellite, nickel-titanium alloy tshwj xeeb yog siv dav. Ua ntej tshaj tawm, lub kav hlau txais xov yog cleverly folded thiab muab zais rau hauv lub satellite lub cev; Tom qab tso tawm, raws li qhov kub thiab txias nce, lub kav hlau txais xov yuav nthuav dav thiab rov qab mus rau qhov zoo li parabolic kom paub meej tias qhov teeb liab kis tau zoo. Dab tsi yog qhov zoo tshaj plaws yog lub kav hlau txais xov tuaj yeem hloov kho lub kaum sab xis raws li xav tau los txhim kho kev ruaj ntseg ntawm kev sib txuas lus thiab qhov tseeb ntawm kev taw qhia. Tsis tas li ntawd, npib tsib xee-titanium alloy kuj tseem siv los ua cov khoom siv hluav taws xob nthuav dav ntawm lub hnub ci tis, muab cov dej khov kho ntawm lub zog txhawb rau satellites.
3. High-pressure gas cylinders: lub lifeline ntawm satellite hwj chim
Nyob rau hauv lub plawv ntawm lub satellite, lub tog raj kheej high-pressure gas cylinders ua los ntawm titanium alloy ntsiag to zov lub satellite lub hwj chim system. Cov cylinders roj no tsis tau tsuas yog txo qhov hnyav xwb tab sis kuj tseem txhim kho lub zog-kev coj tus kheej los ntawm cov txheej txheem titanium thawj zaug mus rau niaj hnub titanium hauv ob sab phlu ntxiv rau cov roj carbon fiber ntau winding composite technology. Lawv muab ib qho kev txhim khu kev qha "gas qhov chaw" rau kev hloov tus cwj pwm thiab kev tsav tsheb ntawm satellites, thiab yog qhov lav rau kev ua haujlwm ruaj khov ntawm satellites. Nyob rau tib lub sijhawm, titanium alloy high-pressure gas cylinders kuj tau siv dav hauv kev tsim cov tsheb thiab cov cuaj luaj, pab txhawb lub zog tseem ceeb rau kev txhim kho kuv lub teb chaws kev lag luam aerospace.
IV. Chaw Lub Koob Yees Duab: "Lub Qhov Muag Ntawm Qhov Chaw" Cast los ntawm Titanium Alloy
Raws li "qhov muag ntawm qhov chaw" rau kev soj ntsuam lub ntiaj teb, kev tsim cov koob yees duab qhov chaw kuj tseem sib cais los ntawm kev txhawb nqa ntawm titanium hlau. Txhawm rau txo qhov hnyav, txhim kho qhov tseeb thiab hloov mus rau qhov chaw ib puag ncig nyuaj, lub lens thav duab, lub lens fwj thiab lub lens mount ntawm cov khoom siv satellite lub koob yees duab yog txhua yam ua los ntawm titanium alloy. Cov koob yees duab no ntes lub sijhawm zoo nkauj ntawm lub ntiaj teb nyob rau hauv qhov chaw thiab nthuav qhia qhov tsis meej ntawm lub ntiaj teb rau peb. Piv txwv li, lub koob yees duab dual-resolution mounted rau ntawm Chang'e 4 relay satellite "Queqiao" yog ua los ntawm titanium alloy thiab ua tiav daim duab ntawm lub ntiaj teb thiab lub hli, qhia txog qhov ua tau zoo ntawm kuv lub teb chaws aerospace technology.
Hauv cov ntsiab lus, titanium hlau plays lub luag haujlwm tseem ceeb hauv kev tsim khoom satellite nrog nws cov txiaj ntsig zoo. Los ntawm "exoskeleton" txhawb nqa satellites mus rau "tus neeg saib xyuas nco" uas ua tiav kev sib txuas lus ruaj khov, los ntawm "lifeline" uas muab lub zog rau "qhov muag ntawm qhov chaw" uas khaws lub sijhawm zoo nkauj, titanium hlau yog nyob txhua qhov chaw uas qhia nws txoj kev ntxim nyiam thiab lub zog. Nyob rau hauv lub neej yav tom ntej qhov chaw taug kev, titanium hlau yuav txuas ntxiv mus ua ib tug loyal phooj ywg ntawm satellites, nrog rau peb mus tshawb lub ntxaum thiab nyob deb ntawm lub ntug.
